摘要
光频多路复用(OFDM)载波通信对提高光纤传输容量和充分利用光纤巨大带宽具有重要意义。OFDM通信的关键技术是复用/去复用技术和光源频率稳定技术。本文对OFDM通信技术及其应用进行了研究、探讨。
Optical frequency-division-multiplexing (OFDM) is effective toincrease optical fiber transmission capacity and utilize its very largebandwidth potential. For OFDM transmission systems, two key technogiesare optical multi/demultiplexing and light source frequency stablization.In this paper, OFDM transmission technique and its application arestudied.
